[0002] In the photovoltaic automation market, the method of directly transporting battery wafers into a quartz boat by a tongue module is generally adopted. An external feeding mechanism transfers the battery wafers on the production line to the quartz boat for storage. The quartz boat is a rack for storing battery wafers. A plurality of material placing grooves are opened from top to bottom on the quartz boat. The material placing grooves are used for receiving battery wafers. After the quartz boat is filled with battery wafers from top to bottom, it enters a processing machine for subsequent processing.

During the transportation process, the battery wafers often interfere and collide with each other, resulting in scratches or even breakage of the battery wafers. The broken battery wafers will also affect the subsequent stacking of battery wafers, and it is necessary to stop the machine for processing, wasting manpower and material resources, and limiting the production efficiency.

Before placing the next battery silicon wafer, the piston rods of the first slide cylinder 501 and the second slide cylinder 502 are extended in sequence, and the fork plate 507 first moves to the bottom of the previous battery silicon wafer, and then lifts the battery silicon wafer upward (the thickness of the discharge trough is greater than the thickness of the battery silicon wafer) to avoid the placement of the battery silicon wafer below, so as to avoid interference, collision and breakage of the battery silicon wafer. After placement is completed, the piston rods of the first slide cylinder 501 and the second slide cylinder 502 are retracted, and the above actions are repeated until the battery silicon wafers are full of the quartz boat 7.
